Property Value

The wreq parameter is optional. If the Request property is set to null or an empty string, the wreq parameter is not included in the sign-in request.

You can override this setting on each HTTP request by adding a handler for the RedirectingToIdentityProvider event. This event is raised just before the module redirects to the security token service (STS) with a WS-Federation sign-in request message. The STS is specified by the Issuer property.
